When using the show bgp ipv6 unicast summary command to verify the IPv6 BGP session status with the IPv6 BGP peers, you noticed the "St/PfxRcd" status for one of the IPv6 BGP peers is in the "Active" state. What does the "Active" state indicate?

• A.The router is in the process of sending BGP routing updates to the IPv6 BGP peer.
• B.The router is exchanging BGP notification messages with its IPv6 BGP peer.
• C.The IPv6 BGP session has been established with the IPv6 BGP peer.
• D.The router is in the process of establishing the IPv6 BGP session with the IPv6 BGP peer.

Refer to the Cisco IOS route map configuration exhibit.

Which two statements are correct? (Choose two.)

• A.All routes that are not matched by the sequence 10 route map statement will be dropped.
• B.The match prefix-list condition is a logical OR: match prefix list PL1 OR PL2.
• C.The local preference AND the metric will be set to 100 IF the route matches the PL1 OR
  PL2 prefix list AND the route must also match the APACL1 AS path access list.
• D.The three match conditions are logical AND. match prefix list PL1 AND PL2 AND match the APACL1 AS path access list.
• E.All match conditions are logical OR: match prefix list PL1 OR PL2 OR match the
  APACL1 AS path access list.

A network engineer implements IS-IS authentication in a router. When the engineer implements the same password on the router's peer, the output below is displayed with the debug IS-IS authentication information:
* Nov 6 13:23:46:967: ISIS-Authinfo: No auth TLV found in received packet
Which option is one reason for this output?

• A.The authentication is set the same way, but the password does not match.
• B.There is an error with the NET address in one of the routers.
• C.The length of the password is not the same.
• D.Authentication was not configured on the router that sent the update.

Refer to the exhibit.
